srnine OILER.

Specification of Letters Patent.

Patented Apr. 111, 11922.

Application filed October 1, 1921. Serial No. 504,703.

To all whom it may concern:

Be it known that I, JAoon K. HERFJORD, a citizen of the United States,and a resident of Sioux City, in the county of Woodbury and State ofIowa, have invented certa n new and useful Improvements in Spring @11-ers, of which the following is a specificatlon.

My invention aims to provide an improved device for greasing vehiclesprings.

Another object of the invention is the pro duction of an improved andsimplified device, inexpensive in production and adapted to be readilyinserted between ad acent leaves of vehicle springs and inject greasethorebetween.

With these and other objects in view, the invention, consisting in theconstruction, combination and novel arrangement of parts, will beclearly understood from the following description, reference being hadto the accompanying drawings, which form a part of this application andin which like characters of reference indicate corresponding partsthroughout the several views, of which:

Fig. l is a plan of a device constructed in accordance with myinvention.

Fig. 2 is a side elevation thereof, and

Fig. 3 is a longitudinal section thereof as applied to a vehicle spring.

The device consists of a bar, 4-, preferably flat-sided and formed atone end with a chisel blade, 5, the bar being cut away abruptly toprovide shoulders, 6, which abut the edges of the springs, as willpresently appear, and adjacent the said shoulders the blade, 5, isformed with flat faces, 7, against which the springs impinge. A distancefrom its chisel end the bar is provided with a lateral opening, 8, intowhich is threaded the nipple, 9, of a grease cup of familiar type, andon to the body, 10, of which is screwed the usual cap or cup, 11. Thecenter of the end of the bar, 5, is notched, as at 12, and alongitudinal grease-way, 13, within the bar, 4t, communicates betweenthe openin 8, and the said notch, 12.

Now, in operation it is only necessary to place the edge of the bar, 5,between adjacent leaves of the spring and the blade driven between thesaid leaves by means of a single blow on the extended end of the bar, l,with a hammer or other suitable tool. T he shoulders, 6, engage theedges of the leaves to prevent the blade from entering too far betweenthe leaves. It will then be clear that by rotating the cap, 11, thegrease will be forced through the passage, 13, and thus introducedbetween the leaves.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent of the United States, is

A greasing device for vehicle leaf springs comprising a bar having achisel-bladed end to be driven between the leaves, a grease injectingcup including body part having a nipple screwed into the side of thebar, and a cover member in screwthreaded connection with the body,whereby rotation of the cover ejects grease from the nipple, and agreaseway in the bar between the nipple and said bladed end.

In testimony whereof, I have hereunto set my hand this 28th day ofSeptember, 1921.

JACOB K. HERFJORD.
